Inertia is the resistance of any physical object to any change in its state of motion. inertia exists due to the mass of the object
Answer:
The hotter the substance, the more its particles move, and the higher its thermal energy. ... Heat. The heat from a heater. *Let's think about that cup of hot chocolate. ... Some matter changes from solid to liquid to gas as its particles heat, vibrate and separate. ... Boiling a kettle is an example of both thermal and kinetic energy.

Answer: The right answer is c.
Explanation:
The kinetic energy is defined as follows:
K = 1/2 mv²
If both cars are identical, this means that they have the same mass.
Also, we are told that the speed is also the same for both cars.
If they are going in opposite directions, their velocities have the same magnitude, but opposite signs.
But even though they have different signs, the square (which is the parameter relevant for kinetic energy calculations), is always positive, as any number, elevated to an even power, is positive.
So, we conclude that both cars have the same kinetic energy, in magnitude and in sign.
